- Optimistic Neurons
In rats given a choice between two rewards, neurons that predict the value of expected rewards responded as though the animal had chosen the best available reward, no matter what the rat actually did.
- Immune Delivery Service
Researchers have identified the cells responsible for rapid delivery of blood-borne antigens to specialized sites in the spleen.

Researchers have identified a protein that blocks the release of chemical mediators that produce the symptoms of allergic reactions.
- Mutation Identified In Neurodegenerative Disorder
Individuals with a neurodegenerative disease called spinocerebellar ataxia 11 (SCA11) have mutations in a gene called TTBK2.
- Gene Prevents Sudden Death In Mice After Infection
Mice that lack a particular gene die suddenly and without overt signs of illness in response to an infection that is usually harmless.
- Normal Cells Lead Tumour Cell Invasion
Normal tissue cells called fibroblasts can help to form a path for invading carcinoma cells, and may thereby promote tumour metastasis.
- Neural Crest Stem Cells On Tap
Human embryonic stem cells have been coaxed into becoming neural crest stem cells, an important cell type in the developing embryo.
- Holding Dormant Cancers In Check
Online paper a crucial stage in the battle between cancer cells and the host's immunce sysen, at which point defences stall the expansion of cancer cells that may have managed to dodge past early immunosurveillance.
- Shaping The Brain's Experience Of The World
New research in rats now shows how the brain goes about the task of reordering to reorganize itself in response to experience.
- Zooming In On Diabetes Susceptibility
A paper reports use of newly available technology and huge numbers of patients to reveal two MHC genes that are implicated in the development of childhood diabetes.

- Genome-Wide RNAi Screen for Regulators of Aging
Insulin signaling found to play an important role in determining organism longevity
- Genetics of Hunger and Sleep
Surprisingly link found between disease of sleep and metabolic control
- Regulation of TATA-less Promoters
Studies show distinct mechanisms control histone gene expression during Drosophila development, revealing new complexity in metazoan gene regulation
2007-11-15
- Abnormal Immune Cells May Cause Unprovoked Anaphylaxis
Until now, in two out of three people, anaphylaxis has had no known cause. Now, researchers have found abnormal immune cells may play a role.
- Unusual Link Between Cell Survival Proteins and Ovarian Cancer Aggressiveness
Apoptosis protein signature might be used to gauge the aggressiveness of a woman’s ovarian tumor at the time of diagnosis.
2007-11-14
- Stalling Chemotherapy Damage
The understanding of how healthy cells cope with damages caused by anti-cancer drugs is furthered by new findings presented online.
- A New Virulence Mechanism For MRSA
Strains of methicillin-resistant staphylococcus aureus (MRSA) that are acquired in the community may be more virulent than hospital-associated strains because they secrete small peptides that disable immune cells.
- Regulating Immune Suppression
Four papers report how white blood cells can produce interleukin 10, a chemical mediator that helps keep the immune response in check.
- Genes For Transplants
A gene that allows mice to accept human bone marrow cells more efficiently is presented online.
- Genetic Mutation In Familial Aortic Aneurysm
Mutations in a gene expressed in smooth muscle cells account for about 14% of cases of hereditary thoracic aortic aneurysm.
- Genetic Variants Associated With Rheumatoid Arthritis
Genetic variants in a region on chromosome 6 are associated with risk of rheumatoid arthritis.
- Primate Patient-Specific Stem Cells
A method of reprogramming rhesus macaque adult fibroblasts into embryonic stem cells using somatic cell nuclear transfer is presented.

New research published helps to fill in the genetic pieces of the jig-saw puzzle associated with the development of the aorta.
- Lung Cancer Characterization
A huge overview of genetic alterations in lung cancer is presented online.
- The Brain In Glorious Technicolor
With a combination of genetic tricks and fancy proteins, researchers have colourfully labelled hundreds of individual neurons with distinctive hues to create a 'Brainbow'.
